In my case, the problem occurred because I was using a network disk for storing my project. When run from this network disk, this problem occurred. I moved the project to my local hard drive and it was gone. I am guessing this has something to do with security, as Windows considers the network drive less secure than my hard disk. share|improve this answer answered Jun 7 '11 at 16:05 GTG 3,85311418 1 Thank you!

Windows Desktop Development > General Windows Desktop Development Issues General discussion 0 Sign in to vote Hello, We have found that since installing the .NET4 framework some http://stackoverflow.com/questions/5168880/error-creating-the-web-proxy-specified-in-the-system-net-defaultproxy-configur .NET applications that need internet connectivity stop working correctly in environments where proxy settings are provisioned via group policy. After looking into it, we have found that a third party application, RM Management Console, is able to create a GPO with an invalid proxy address port number ie. the port number is suffixed with a ‘;’. This was definitely not an issue for the .NET2 framework however as soon as https://social.msdn.microsoft.com/Forums/en-US/b29a661a-8226-4721-87f8-d49847cc4831/error-creating-the-web-proxy-specified-in-the-systemnetdefaultproxy-configuration-section?forum=windowsgeneraldevelopmentissues the .NET4 is installed a ConfigurationErrorsException is thrown (in all the versions of the framework): “Error creating the Web Proxy specified in the 'system.net/defaultProxy' configuration section.” The best way to solve this, it is to remove the semicolon from the GPO using the Microsoft Management Console. Did anyone else experience this?

Project which I was running and which was trying to reach the Web Service was on a network share. Copying that project to my machine and running it locally solved problems.
